## Abstract

Disclosed herein is a battery pack. The battery pack can include a plurality of battery cells, a pack case defining a housing configured to accommodate the battery cells, a first venting path extending across the pack case, and a second venting path extending along at least one peripheral side of the pack case. The first venting path can provide a conduit for a gas generated from any of the battery cells. The second venting path can be in fluid communication with the first venting path and an opening on the pack case such that the gas from the battery cells is configured to travel from the first venting path to the second venting path and to be discharged from the battery pack via the opening.

## Claims

### Claim 1

A battery pack comprising:
a plurality of battery cells;
a pack case defining a housing configured to accommodate the battery cells;
a first venting path extending across the pack case, the first venting path providing a conduit for a gas generated from any of the battery cells, and
a second venting path extending along at least one peripheral side of the pack case,
wherein the second venting path is in fluid communication with the first venting path and an opening on the pack case such that the gas from the battery cells is configured to travel from the first venting path to the second venting path and to be discharged from the battery pack via the opening.

### Claim 2 (depends on 1)

The battery pack of claim 1, further including a cooling tube in contact with the battery cells, the cooling tube contacting the pack case such that heat generated by any of the battery cells is configured to be transferred via the cooling tube to the pack case by conduction and discharged from the pack case.

### Claim 3 (depends on 2)

The battery pack of claim 2, wherein the heat being discharged from the pack case is discharged by convection.

### Claim 4 (depends on 3)

The battery pack of claim 3, wherein the heat transfer from the battery cell to the pack case is conducted via a structure of the second venting path to the pack case.

### Claim 5 (depends on 4)

The battery pack of claim 4, further including a heat transfer member forming a bridge between the cooling tube and the pack case.

### Claim 6 (depends on 4)

The battery pack of claim 4, wherein the first venting path is in fluid communication with the second venting path via a venting hole.

### Claim 7 (depends on 1)

The battery pack of claim 1, wherein the opening is a venting valve.

### Claim 8 (depends on 7)

The battery pack of claim 7, wherein the venting valve is configured to forcibly discharge the gas from the pack case.

### Claim 9 (depends on 1)

The battery pack of claim 1, wherein the battery cells are accommodated in the housing in a linear array.

### Claim 10 (depends on 1)

The battery pack of claim 1, wherein the second venting path is perpendicular to the first venting path.

### Claim 11 (depends on 1)

The battery pack of claim 1, wherein the first venting path is defined by the pack case and a bottom plate.

### Claim 12

A battery pack comprising:
a plurality of battery cells;
a pack case defining a housing configured to accommodate the battery cells, and
a cooling tube in contact with the battery cells, the cooling tube contacting the pack case,
wherein heat generated by any of the battery cells is configured to be transferred via the cooling tube to the pack case by conduction and discharged from the pack case to an outside via convection.

### Claim 13 (depends on 12)

The battery pack of claim 12, further including a first venting path extending across the pack case, the first venting path providing a conduit for a gas generated from any of the battery cells, a second venting path extending along at least one peripheral side of the pack case, wherein the second venting path is in fluid communication with the first venting path and an opening on the pack case such that the gas from the battery cells is configured to travel from the first venting path to the second venting path and to be discharged from the battery pack via the opening.

### Claim 14 (depends on 13)

The battery pack of claim 13, wherein the heat being discharged from the pack case is discharged by convection.

### Claim 15 (depends on 14)

The battery pack of claim 14, wherein the heat transfer from the battery cell to the pack case is conducted via a structure of the second venting path to the pack case.

### Claim 16 (depends on 15)

The battery pack of claim 15, further including a heat transfer member forming a bridge between the cooling tube and the pack case.

### Claim 17 (depends on 16)

The battery pack of claim 16, wherein the first venting path is in fluid communication with the second venting path via a venting hole.

### Claim 18 (depends on 13)

The battery pack of claim 13, wherein the opening is a venting valve.

### Claim 19 (depends on 18)

The battery pack of claim 18, wherein the venting valve is configured to forcibly discharge the gas from the pack case.

### Claim 20 (depends on 13)

The battery pack of claim 13, wherein the battery cells are accommodated in the housing in a linear array.
